Minted a NFT on Rinkeby, sent it to my Metamask. Now I want to send it to another account for testing but, “send” is greyed out.

I minted a NFT on Rinkeby a few hours ago. I actually have 4 tokens. You can see them here

https://rinkeby.etherscan.io/address/0xc6f701adfb3f1b0a30957f475823351dB5c9EDCE#tokentxnsErc721

But when I go to my wallet to send them on to another wallet I use for a project, I can't send them. “Send” is greyed out. See:

How do I send this NFT to myself?

Could it be because I wrote “0” for the decimal value of the NFT's token decimal when adding it?
